how to configure multiple monitors?

[drdna]

i have acer notebook with intel 915GM chipset, and a LG 17" CRT.



i tried to configure to dual display system, but it doesn't seem to be
working. can't figure out what's wrong.



somebody help me.



this is my xorg.conf file:



# /etc/X11/xorg.conf (xorg X Window System server configuration file)

#

# This file was generated by dexconf, the Debian X Configuration tool,
using

# values from the debconf database.

#

# Edit this file with caution, and see the /etc/X11/xorg.conf manual
page.

# (Type "man /etc/X11/xorg.conf" at the shell prompt.)

#

# This file is automatically updated on xserver-xorg package upgrades
*only*

# if it has not been modified since the last upgrade of the
xserver-xorg

# package.

#

# If you have edited this file but would like it to be automatically
updated

# again, run the following command:

#   sudo dpkg-reconfigure -phigh xserver-xorg
